Pressure-welded steel grating consists of load-bearing flat bars and crossbars arranged in a grid pattern at specific intervals. Utilizing automated 200-ton hydraulic resistance welding equipment, these components are fused into a master panel, which then undergoes processes such as cutting, notching, and edging to produce a finished product tailored to customer specifications.
Load-bearing Flat Bar Spacing: The center-to-center distance between two adjacent load-bearing flat bars; common spacings are 30mm and 40mm.
Crossbar Spacing: The center-to-center distance between two adjacent crossbars is typically 50mm or 100mm, though custom spacings can be produced according to customer requirements.
Compared to checkered steel plates and other types of grating, steel grating offers the following advantages:
Material Efficiency: Under equivalent load-bearing conditions, it represents the most material-efficient solution; consequently, it also reduces the material requirements for the supporting structure.
Reduced Investment: Saves on material costs, labor, and construction time, while requiring virtually no cleaning or maintenance.
Ease of Installation: Can be secured to pre-installed support structures using bolt clips or welding; the entire process can be completed by a single person.
Time Savings: The product requires no further on-site processing, allowing for extremely rapid installation.
Durability: Prior to shipment, the product undergoes hot-dip galvanizing for corrosion protection, offering strong resistance to impact and heavy loads.
Modern Aesthetics: Features an attractive appearance and standardized design; its open structure facilitates ventilation and natural lighting, creating a cohesive, modern aesthetic.
Lightweight Structure: Requires minimal material, resulting in a lightweight structure that is easy to hoist and position.
Self-Cleaning: Prevents the accumulation of rainwater, snow, ice, and dust.
Reduced Wind Resistance: Due to its excellent ventilation properties, it offers minimal wind resistance during high winds, thereby reducing the risk of wind-related structural damage.
Simplified Design: Eliminates the need for secondary support beams, resulting in a simpler overall structure and streamlined design process. Detailed grating drawings are unnecessary-simply specifying the model number suffices, as the manufacturer can generate the panel layout drawings on behalf of the client.
Excellent Performance: Offers superior ventilation, natural lighting, heat dissipation, explosion resistance, and anti-slip properties.
Acid and Alkali Resistance: Within a pH range of 6.0 to 12.5, the surface zinc coating forms a stable protective film, ensuring excellent corrosion resistance.
